A little background to aid understanding and a pointer to a way forward.

Your laptop actually only has one and half video systems. The complete one is the Intel graphics system.
It can both draw new images in the pixel buffer and read them out to refresh the display.
The half a video system is the nvidia video system. It can only draw new images in the pixel buffer. It is not connect to the display at all, hence when you try to use the nvidia-drivers you get a blank screen and a log full of errors.

To use the nvidia graphics system, the Intel graphics must be used to redraw the screen - the graphics systems must cooperate.

I understand that, and I tested bumblebee before, but the performance was not good. If I understand... a few moths ago, NVIDIA released a Driver(>=319.12) with optimus "native support" on Linux (Not more bumblebee). People that installed and configured it succesfully say that performance is better than NVIDIA + BUMBLEBEE. I don't know if that is true. I like to prove it myself, but i can't do it work. .

Anyway, I have a question... I still need bumblebee with the "new driver"?._________________--

However, if the nvidia-drivers package was all you needed (no bumblebee) it would need to be able to configure the Intel graphics card too.
Its perfectly possible to do that, as xf86-video-intel is open source but it would make the nvidia-drivers very messy.

but /usr/share/doc/nvidia-drivers-325.15/README.bz2 Chapter 18. Using the NVIDIA Driver with Optimus Laptops, says

Quote:

... As an alternative to using only the integrated graphics device, support for
the display output source functionality provided by the X Resize and Rotate
extension version 1.4 is available. This functionality allows for graphics to
be rendered on the NVIDIA GPU and displayed on the integrated graphics device.
For information on how to use this functionality, see Chapter 33.

The interesting reading is in Chapter 33, so the nvidia-driver can work almost the way you would like ... but not quite and not without the Intel driver._________________Regards,
